ALBERT MOFFE'I, OF BRISTOL, OHIO.

MACHINE FOR MARKING WAVING PATTERNS.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, ALBERT MOFFET, of Bristol, in the county of Trumbulland State of Ohio, have invented new and useful Improvements in anAutomatic Scroll- Gage for Laying Out Vinework, Oog-'Wheels &c.; and Ido hereby declare that the following is a full and complete descriptionof the construction and operation of the same, reference being had tothe accompanying drawings, making part of this specification, in which-Figure 1, is a top View. Fig. 2, is a side view. Fig. 3, is an end view,and Fig. 4, is a View of the side opposite that seen in Fig. 2. v

Like letters refer to like parts in the several views.

The nature of my invention relates to an arrangement of devices, bymeans of which a regular vine scroll can be laid off, or be caused tovary in its depth, by changing continually and gradually the fulcrum ofthe arm that carries the pencil or marking point, or by changing thegears, a longer or shorter scroll can be laid out, or by making thefulcrum stationary, a regular vine, or

.cog gear can be laid out.

A, in the several figures, represents the frame of the machine. This maybe made of wood, in length about fifteen inches, and in depth about twoand a half inches. The wheels and other parts are in proportion.

B, in the several figures, is a spurred wheel, that is, its face isfilled with sharp points. It can therefore be run along the surface of aboard without slipping, and by this means, motion is given to otherparts.

O, is a stop or guide (there is another not shown, at the opposite endof the machine,) that slides along the edge of the board upon which thescroll is marked.

D, is a cog wheel, placed upon the same shaft with the wheel B, seen atB, and upon which it is adjustable, so as to gear into either of thewheels E, F, G, the wheel F, being smaller than E, and G, smaller' thanF. The shaft B must consequently be capable of adjustment toward thewheels E, F, Gr, which are all upon the shaft H. The bearings of theshaft B, are therefore, provided with a slot I, by means of which theshaft can be moved toward the shaft I-I.

There is an upright spur wheel J, that is put in motion by the gear E,in the side of the wheel E. The wheel J, is provided with a pin or wristK, which moves in the slot L, in the lever M, the fulcrum of which29,901, dated September 4, 1860.

is movable and seen at N, in the sliding bar O. The long arm of thelever is slotted, as seen in Fig. 1, so that the fulcrum N, can movenearer to, or farther from the wheel J. The sliding bar O, is moved outand in at every revolution of the wheel P, by means of the band P, andwheel Q, and connecting rod P, the wheel I), being put in motion by theband wheel Q, as shown in Fig. 1, which wheel Q is attached to the endof the shaft B, and not shown in Fig. 4. The pin of the connecting rodcan be changed nearer to or farther from the center of the wheel P, asindicated by the holes a b c d, by which the distance the sliding bar ismoved, is governed.

S, is an arm that carries the marking point, which is introduced intothe arm S, at S.

T, is a guide for the arm S. The arm S, is attached to, and moved by ajointed finger V, which is connected to the arm M, at N.

V, is a guide which prevents the arm M from moving lengthwise.

The manner of using this machine is as follows: If a regular vine is tobe marked off on the edge of the board, the stops C, are caused to slidealong` the edge of the board, while the spurred wheel B, rolls along theface of the board. The wheel J, is thereby put in motion, and the arm S,is moved out and in, at right angles to the course of the machine. Thepencil, or point at S, will consequently mark a scroll or vine, withregularity, provided the fulcrum remains stationary; but if the fulcrumN, is caused to move, or traverse backward and forward, by means of therevolution of the wheel P, the scroll or vine will be irregular. Theundulations of the scroll, may therefore be made long or short, regularor irregular, as the operator may wish, changing the action of themachine at pleasure, by changing the wheel D, to E, F or G, and byincreasing or diminishing the traverse of the sliding bar O, or makingthe fulcrum N, stationary.

lVhat I claim as my improvement, and desire to secure by LettersPat-ent, ish

1. The lever M, sliding bar O, and arm S, arranged and operated in themanner and for the purpose specified.

2. The moving' fulcrum il in combination with the connecting rod P andwheel P, operated as, and for the purpose specified.

ALBERT MOFFET.
